Description
BACKGROUND
[0001] Electroluminescent (EL) wire is a special type of wire which
is commercially available off-the-shelf from a variety of
suppliers. It is generally made up of a concentric series of
layers, each of which performs a different function. The center
layer consists of a copper core which is coated with an EL phosphor
material. Fine-gauge wires, which are electrically connected
together at one or more points, are then wrapped around this center
layer, and then a translucent colored plastic coating and
insulation coating are applied on top of the wrapped core. EL wire
is "illumable" (i.e., it can be made to emit light). When an AC or
DC electrical signal (hereafter simply referred to as an electrical
signal) is applied between the copper core and the fine-gauge wires
at the proper voltage (and frequency if an AC signal is involved),
the phosphor material glows and hence, the EL wire emits light in
the basic color of the plastic coating. Since different colored
plastic coatings can be applied to the wire, different types of EL
wire can be purchased which emit different colors of light. The
brightness level of the light that is emitted is basically a
function of the voltage level (and frequency if an AC signal is
used) applied to the wire. In general, the higher the voltage (and
frequency) applied to the wire, the greater the brightness of the
light that is emitted. With some types of EL wire, the color of the
light that is emitted can also be varied somewhat by varying the
frequency if an AC signal is used.
[0002] A salient feature of EL wire is that it generally exhibits a
small amount of latency between when the electrical signal is
applied to the wire and when it starts to emit light, and also
between when the electrical signal is removed from the wire and
when it stops emitting light. Hence, EL wire is suitable for
lighting applications where transient flashes of light or a strobe
light effect are desired. Another salient feature of EL wire is
that it is pliable. Hence, EL wire is suitable for a broad range of
lighting applications where it is necessary for the light source to
take on a certain shape or geometry. EL wire is also available in a
range of different diameters (i.e., gauges), however, in general,
the greater the diameter of the wire the lower its degree of
pliability.
SUMMARY
[0003] The present invention is directed toward a display device
that utilizes electroluminescent (EL) wire for displaying
user-configurable information. The display device generally
includes an array of pegs to retain the EL wire in a variety of
user-configurable geometric patterns. More particularly, the
present invention is embodied in a display device that utilizes one
or more individual segments of EL wire, each segment with
potentially a different length and diameter and in potentially a
different color, to display custom information generated by a
user's shaping of the EL wire segments into a desired geometric
pattern. The geometric pattern is generated by the user's routing
of each EL wire segment (hereafter referred to as an EL wire)
through an array of pegs located within a viewable window on the
display device. The routed pattern of EL wires is maintained in
place, in the event of display device movement, or impact or
vibration to the display device, via novel peg designs which are
described in detail below in the Detailed Description. The color,
length, diameter and routing pattern of each EL wire are selected
by the user based on the specific content of the information they
want to display. The information displayed can easily be
reconfigured either by the user's re-routing of existing EL wires
through the array of pegs, or by their routing of new EL wires
through the array of pegs. Each EL wire is plugged into a connector
located in a series of one or more connectors that borders one or
more edges on the periphery of the display device. The connectors
are hidden underneath border strips which frame all the edges on
the periphery of the display device. Each border strip is
independently hinged in order to provide the user access to the
underlying connectors.
[0004] Furthermore, the present display device is self-contained,
portable and can be placed in any physical orientation. The display
device can also be mounted for viewing in a variety of ways,
including setting it either on its rear side or along one of its
edges on a horizontal supporting surface such as an easel, shelf or
table, or hanging it in a window, on a wall, or other vertical
supporting surface, among others. The display device is
electrically powered either by internal batteries or an external
power supply. The EL wires are "illumable" (i.e., they can be made
to emit light). A control module is included inside the display
device which supplies an independently controlled electrical signal
to each of the aforementioned connectors. Each connector in turn
supplies its electrical signal to the EL wire that may be plugged
into the connector, which causes the wire to emit light in a color
corresponding to the specific wire. The control module
independently controls the brightness and timing pattern of the
light emitted by each EL wire plugged in by independently
controlling the characteristics of each electrical signal supplied
to each connector. The user can select from a variety of display
modes, and adjust the overall display sensitivity and brightness,
via user controls located on the periphery of the display device.
By way of example but not limitation, in one particular display
mode the EL wires emit light continuously at a prescribed level of
brightness. In another particular display mode the EL wires emit
transient flashes of light in synchronization with changes in the
frequency and/or amplitude of an external signal supplied to the
display device from a microphone. In yet another particular display
mode the EL wires emit transient flashes of light in
synchronization to changes in the frequency and/or amplitude (i.e.,
the "beat") of an external signal supplied to the display device
from an audio source. The display device also includes additional
display modes which are described in the Detailed Description
below.
[0005] The present display device can be used to create and display
a variety of types of information. The display device can also be
used for a variety of purposes in a wide range of different markets
and applications such as the novelty, toy, recreation, art and
commercial signage markets, among others.

DETAILED DESCRIPTION
[0020] In the following description of embodiments of the present
invention reference is made to the accompanying drawings which form
a part hereof, and in which are shown, by way of illustration,
specific embodiments in which the invention may be practiced. It is
understood that other embodiments may be utilized and structural
changes may be made without departing from the scope of the present
invention.
[0021] In general, the present invention relates to a display
device that utilizes electroluminescent (EL) wire for displaying
user-configurable information. The display device includes an array
of pegs to retain the EL wire in a variety of user-configurable
geometric patterns. More particularly, the present invention is
embodied in a display device that utilizes one or more individual
segments of EL wire, each segment with potentially a different
length and diameter and in potentially a different color, to
display custom information generated by a user's shaping of the EL
wire segments into a desired geometric pattern. In general, the
geometric pattern is generated by the user's routing of each EL
wire segment (hereafter referred to as an EL wire) through an array
of pegs located in a viewable window on the display device. The
routed pattern of EL wires is maintained in place, in the event of
display device movement, or impact or vibration to the display
device, via novel peg designs which are described in detail below.
The display device is self-contained, portable, can be placed in
any physical orientation, and can be mounted for viewing in a
variety of ways which are described in detail below. The EL wires
in the display device are "illumable" (i.e., they can be made to
emit light). The brightness and timing pattern characteristics of
the light emitted by each EL wire are controlled by a control
module included inside the display device, in combination with a
variety of user controls which are located on the periphery of the
display device. The control module also serves to operate the
display device in a variety of display modes, each of which is
described in detail below.
[0022] The present display device can be used to create and display
a variety of types of information including but not limited to
letters, numbers, symbols, shapes and characters in any size,
combination and physical orientation. The display device can also
be used for a variety of purposes in a wide range of different
markets and applications such as the novelty, toy, recreation, art
and commercial signage markets, among others.
[0023] FIG. 1 shows an exemplary front view of one embodiment of
the present display device. The display device includes a
self-contained display module 1 which is electrically powered
either by batteries (not shown) installed into a battery
compartment (not shown) located inside the display module 1, or by
an external power signal 2 which is supplied by a conventional
power adapter module (not shown) located external to the display
module 1. The external power signal 2 connects to the display
module 1 via an electrical cable (hereafter referred to as a
cable--not shown) that plugs into a power connector 3 located on
the periphery of the display module 1. One or more EL wire
connectors 8 border one or more of the edges on the periphery of
the display module 1. One or more EL wires 9, each including a
resilient connector (not shown) on one end which is designed to
mate with the connector 8 and retain the EL wire 9 in the connector
8, can be plugged into the EL wire connectors 8 and routed through
an array 14 of pegs 10 located within a viewable window 11 on the
front of the display module 1. The color, length, diameter and
geometric routing pattern of each EL wire 9 can be independently
selected and varied by the user based on the specific content of
the information they want to portray on the display device. The
maximum allowable EL wire diameter is dictated by the spacing
between the pegs 10 in the array 14.
[0024] Referring again to FIG. 1, all the edges on the periphery of
the display module 1 are framed by border strips 7 which serve to
hide and protect the EL wire connectors 8 which may lie underneath,
and also to improve the visual appearance of the display device.
Each border strip 7 is independently hinged onto the display module
1 by one or more hinges (hinges are not shown) located along the
coincident peripheral edges of the border strip 7 and the display
module 1. The user can lift the inside edge of the border strip 7,
hence rotating it up along its hinge(s) away from the array 14 of
pegs 10, in order to gain access to the underlying EL wire
connectors 8. After lifting a border strip 7, an EL wire 9 is
plugged by the user into one of the exposed EL wire connectors 8
and from there the EL wire 9 is routed by the user through the
array 14 of pegs 10 to create their desired geometric pattern. This
process is continued for each individual EL wire 9 until the user
has completed all of the EL wire 9 selections and routing needed to
create the information content they want to portray on the display
device. The information displayed can easily be reconfigured either
by the user's re-routing of existing EL wires 9 through the array
14 of pegs 10, which may include moving existing EL wires 9 to new,
unused EL wire connectors 8 either located underneath the same
border strip 7 or a different border strip 7, and/or by the user's
plugging additional new EL wires 9 into the EL wire connectors 8
and routing the new EL wires 9 through the array 14 of pegs 10.
[0025] Referring yet again to FIG. 1, a control module (not shown)
is included inside the display module 1 which serves, in
conjunction with a variety of user controls located on the
periphery of the display module 1, to control all of the electrical
features and display mode features of the display device. These
user controls, electrical features and display mode features will
now be described in detail. The control module supplies an
independently controlled electrical signal to each EL wire
connector 8, which in turn supplies the electrical signal to an EL
wire 9 which may be plugged into the connector 8. The electrical
signal causes the EL wire 9 to emit light in a color corresponding
to the specific characteristics of that particular wire 9. The
control module independently controls the brightness level and
timing pattern of the light emitted by each EL wire 9 plugged into
the display module 1 by independently controlling the voltage level
(and frequency if an AC signal is used) of the electrical signal
supplied to each connector 8, and independently turning the
electrical signals on and off. The user can turn the overall
display module 1 on and off via a display mode switch 5 located on
the periphery of the display module 1. As discussed in detail
below, the display mode switch 5 is also used to select a
particular operating display mode for the display module 1. A test
button 4 is also located on the periphery of the display module 1.
Assuming the display mode switch 5 is in a position other than the
off position, when the user depresses the test button 4 the display
mode that the display module 1 is currently operating in is
temporarily overridden and all the EL wires 9 continuously emit
light until the user releases the test button 4, after which the
display module 1 returns to operating in the display mode set by
the display mode switch 5. This on-demand temporary test mode is
useful to allow the user to quickly preview their information on
the display module 1.
[0026] Referring yet again to FIG. 1, the user can select from a
variety of display modes via a display mode switch 5 also located
on the periphery of the display module 1. By way of example but not
limitation, in one particular display mode all the EL wires 9
plugged into the display module 1 emit light continuously at a
prescribed brightness level (referred to hereafter as the
"constant-on" display mode). In another display mode all the EL
wires 9 flash on and off in unison at a prescribed duty cycle
(referred to hereafter as the "constant-flash" display mode). In
yet another display mode each EL wire 9 flashes on and off randomly
(referred to hereafter as the "random-flash" display mode). In yet
another display mode, the EL wires 9 flash on and off in
synchronization with changes in the frequency and/or amplitude of a
microphone signal 13 which is supplied to the display module 1 by a
conventional microphone (not shown) located external to the display
module 1 (referred to hereafter as the "microphone-sync" display
mode). The microphone signal 13 connects to the display module 1
via a cable (not shown) that plugs into a microphone connector 12
located on the periphery of the display module 1. In yet another
display mode, the EL wires 9 flash on and off in synchronization to
changes in the frequency and/or amplitude (i.e., the "beat") of an
auxiliary audio signal 15 which is supplied to the display module 1
by one of a variety of possible audio sources (such as a CD player,
MP3 player or radio, among others--not shown) located external to
the display module 1 (referred to hereafter as the "audio-sync"
display mode). The auxiliary audio signal 15 connects to the
display module 1 via a cable (not shown) that plugs into an
auxiliary audio connector 16 located on the periphery of the
display module 1. A sensitivity control dial 6 is located on the
periphery of the display module 1, which can be used by the user to
adjust the sensitivity of the control module (not shown) in
particular display modes. By way of example but not limitation, in
the constant-flash display mode the sensitivity control dial 6 can
be used to adjust the rate at which the EL wires 9 flash. In either
the microphone-sync or audio-sync display modes the sensitivity
control dial 6 can be used to adjust the sensitivity of the control
module (not shown) to either the microphone signal 13 or the
auxiliary audio signal 15.
[0027] FIG. 2 shows an exemplary cross-section view of one
embodiment of one of the pegs 10 on the display module 1 of the
present display device along with two EL wires 9 which are routed
along either side of the peg 10. Each peg 10 includes two sections,
a post 21 and a cap 20. In one embodiment, the post 21 is
cylindrically shaped and serves to channel the routing of the EL
wires 9. The proximal end 22 of each post 21 attaches to the array
14. The cap 20 attaches to the distal end 23 of each post 21. In
one embodiment, the cap 20 is cylindrically shaped with a domed top
and bottom surface. The cap 20 has a circumference that is larger
than the circumference of the post 21 in order to retain the EL
wires 9 routed adjacent to the post 21 in place under the cap 20.
This inhibits the EL wires 9 from slipping over the peg 10, hence
maintaining the user's EL wire routing patterns, in the event that
the display module 1 is subjected to movement, impact or vibration.
As discussed in more detail below, the post 21 and cap 20 can
either be constructed together as a single part, or alternatively,
the cap 20 can be constructed as a separate part which is plugged
onto the post 21 by the user.
[0028] FIG. 3 shows an exemplary rear view 30 of one embodiment of
the display module 1 of the present display device. The rear side
of the display module 30 is solid in construction serving to
provide a rigid structure on which the rest of the display module 1
is built, and also to enclose and protect the contents located
inside the display module 1. The rear side of the display module 30
also provides access to a battery compartment 31, which is normally
shielded by a removable cover (detail of which is not shown) which
serves to protect the batteries 32 and retain them in place in
their respective holders (detail of which are not shown). By
removing the cover the user can gain access to the battery
compartment 31 in order to remove existing batteries 32 and/or
install new batteries 32 as needed.

possible in which the quantity and locations of the EL wire
connectors 8 is varied.
[0030] The array 14 of pegs 10 of the present display device can be
implemented in a variety of ways. In one embodiment the array of
pegs has a base plate that pegs extend from. In another embodiment,
an interlocking strip arrangement is employed. FIG. 5 shows an
exemplary front view of this latter embodiment of the array 14 of
pegs 10 in which the array 14 is made up of a number of
interlocking strips of pegs 51 which are joined together
side-by-side. Each strip of pegs 51 includes a series of pegs 10
which are located on the top of the strip 51. As discussed below,
the strip of pegs 51, the pegs 10, and the method by which the pegs
10 are attached to the strip of pegs 51 can each be implemented in
a variety of ways.
[0031] FIG. 6 shows an exemplary cross-section view of one
embodiment of the strip of pegs 51 shown in FIG. 5, termed strip of
pegs-A 60. Strip of pegs-A 60 has a unitary construction which
includes one or more posts 63 whose proximal ends are permanently
attached to the top of the strip of pegs-A 60, and caps 64
permanently attached to the distal ends of each of the posts 63.
Furthermore, strip of pegs-A 60 includes a protruding feature 61
disposed onto one of its side edges and a matching detent feature
62 disposed onto the other of its side edges which serve to allow
multiple strip of pegs-As 60 to be joined together side-by-side in
a self-aligning, interlocking fashion.
[0032] FIG. 7 shows an exemplary cross-section view of one
embodiment of three strip of pegs-As 60 joined together
side-by-side in self-aligning, interlocking fashion. A variety of
array 14 sizes and related display module I sizes can be produced
by constructing each strip of pegs-A 60 to a desired length and
joining a desired quantity of strip of pegs-As 60 together.
[0033] It is noted that while the various foregoing peg
configurations were described in connection to their implementation
in the interlocking strip embodiment, they could also be
implemented in the embodiment of the peg array employing a base
plate.
[0034] As stated above, the present display device can be placed in
any physical orientation and can be mounted for viewing in a
variety of ways. By way of example but not limitation, the display
module 1 can be placed along its rear side on a horizontal surface
such as a table for vertical viewing from above. The display module
1 can also be placed along its rear side on a horizontal surface
such as a ceiling for vertical viewing from below. The display
module 1 can also be placed along one of its peripheral edges on a
horizontal surface such as an easel, shelf or table for horizontal
viewing. The display module 1 can also be hung from or fastened to
vertical surface such as a wall or window for horizontal
viewing.
[0035] While the present invention has been described in detail by
specific reference to embodiments thereof, it is understood that
variations and modifications thereof may be made without departing
from the true spirit and scope of the present invention. For
example, referring to FIGS. 1, 5, 6 and 7, in one embodiment of the
present display device described above, the display module 1 has a
rectangular shape, a certain quantity of EL wire connectors 8 are
located on each of the peripheral edges of the display module 1,
and the array 14 of pegs 10 is implemented via joining together
self-aligning, interlocking strips of pegs 51/60 which have a
unitary construction that includes the proximal end of posts 63
permanently attached to the top of each strip of pegs 51/60 and
caps 64 permanently attached to the distal end of each post 63.
Furthermore, the array 14 of pegs 10 is arranged in a rectangular
grid with uniform spacing between all the pegs 10. All of these
characteristics can be modified in the ways described below to
create alternate implementations of the display device depending on
the needs of a specific type of market or application that the
display device is targeted towards, and the specific content of the
information that may be displayed in said market or
application.
[0036] In another embodiment of the display device, the display
module can have a variety of other shapes, including a triangular
shape, square shape, hexagonal shape, or circular shape, among
others.
[0037] In yet another embodiment of the display device, the
cross-sectional area of the post section of the pegs in the array
of pegs can have a variety of shapes, including a triangular shape,
square shape, hexagonal shape, or circular shape, among others.
[0038] In yet another embodiment of the display device, the cap
portions of the pegs in the array of pegs can have a variety of
shapes other than the modified spherical shape described
previously. For example, the cap could have a substantially cubic
shape, or pyramidal shape, or a disk shape, among others. In regard
to the disk shaped embodiments, the disk could have a cylindrical,
square, triangular, or any other appropriate cross-sectional area
when viewed from above.
[0039] In yet another embodiment of the display device, the cap
portions of the pegs in the array of pegs are eliminated and just
the post is employed.
[0040] In yet another embodiment of the display device, EL wire
connectors can be located on only a subset of the peripheral edges
of the display module.
[0041] In yet another embodiment of the display device, the
quantity of EL wire connectors can be varied and a different
quantity of EL wire connectors can be located on each of the
peripheral edges of the display module.
[0042] In yet another embodiment of the display device, EL wire
connectors can be located anywhere within the array of pegs, and if
desired, anywhere along the peripheral edges of the display module
as well.
[0043] In yet another embodiment of the display device, the array
of pegs can be arranged in a variety of other patterns which
utilize a variety of other peg spacing manifestations including
ones in which the spacing between pegs is varied.
[0044] In yet another embodiment of the display device, a
brightness control dial 17 (shown in FIGS. 1, 3 and 4) can be added
to the periphery of the display module 1 which would enable the
user to adjust the brightness level of the light emitted by all the
EL wires 9 in common, independent of the particular display mode
that the display module 1 is operating in. Referring specifically
to FIG. 4, the brightness control dial 17 is connected to the
control module 41 via cable 46.
[0045] In yet another embodiment of the display device, strip of
pegs 51 is implemented as shown in FIGS. 9A and 11. More
particularly, FIG. 11 shows an exemplary cross-section view of
another embodiment of strip of pegs 51, termed strip of pegs-B 110,
which includes one or more holes 111 constructed into the top of
the strip of pegs-B 110. FIG. 9A shows an exemplary cross section
view of another embodiment of peg 10, termed peg-A 90. Peg-A 90 is
a stand-alone part that has a unitary construction which includes a
cap 91 permanently attached to the distal end of a post 92. The
user can plug the proximal ends 93 of peg-As 90 into one or more
holes 111, thus creating a customized peg layout pattern on the
display device which they can subsequently easily reconfigure as
desired.
[0046] In yet another embodiment of the display device, strip of
pegs 51 is implemented as shown in FIGS. 9B and 11. More
particularly, FIG. 11 shows an exemplary cross-section view of
another embodiment of strip of pegs 51, termed strip of pegs-B 110,
which includes one or more holes 111 constructed into the top of
the strip of pegs-B 110. FIG. 9B shows an exemplary cross section
view of another embodiment of peg 10, termed peg-B 97. Peg-B 97 is
a stand-alone part that has a unitary construction which includes a
cap 99 permanently attached to the distal end of a pin 95. The user
inserts pin 95 completely into a hole 111 so that just cap 99
extends above the top of the strip of pegs-B 110. The pegs-B 97 can
be placed so as to create a customized peg layout pattern on the
display device which can subsequently be easily reconfigured as
desired. However, in this embodiment, the cap 99 has a slot 96 at
its distal end that an EL wire fits into and is held in place by,
rather that the wire being routed around the aforementioned posts.
The slots 96 of the peg caps 99 are oriented to facilitate the
routing of the EL wire secured therein.
[0047] In yet another embodiment of the display device, strip of
pegs 51 is implemented as shown in FIG. 10. More particularly, FIG.
10 shows an exemplary cross-section view of another embodiment of
strip of pegs 51, termed strip of pegs-C 101 and cap-A 102. Strip
of pegs-C 101 includes one or more posts 104 whose proximal ends
are permanently attached to the top of the strip of pegs-C 101.
Cap-A 102 is a stand-alone part which includes a hole 103
constructed into the bottom of the cap-A 102. The user can plug
cap-As 102 onto one or more of the distal ends 105 of posts 104,
thus creating a customized peg layout pattern on the display device
which they can subsequently easily reconfigure as desired.
[0048] In yet another embodiment of the display device, the array
14 of pegs is implemented as shown in FIGS. 8 and 9. FIG. 8 shows
an exemplary front view of another embodiment of the array 14 of
pegs in which a plurality of holes 81 are constructed, in a
prescribed pattern, into a single plate 82 which is constructed in
the prescribed shape of the display device. The user can plug the
proximal ends 93 of peg-As 90 into one or more of the holes 81,
thus creating a customized peg layout pattern on the display device
which they can subsequently easily reconfigure as desired.
[0049] In yet another embodiment of the display device, any of the
peg configurations described previously that include a post also
include a narrowed section near the proximal end of the post. This
narrowed section allows the post to bend more easily so as to
facilitate the insertion and routing of the EL wires. In addition,
the narrowed section allows the post to deflect once the EL wire is
installed so that the wire can bend around a post with a less
extreme radius allowing for more curved appearance of the routed
wire.
[0050] In yet another embodiment of the display device, the
previously described border strips are eliminated. This embodiment
could be employed in an arrangement of multiple electroluminescent
wire display devices. For example, a wall, or a part thereof, could
be covered with multiple display devices in an abutting pattern. Of
course, a group of the display device embodiments having border
strips could also be arranged in this fashion as well.
[0051] Referring to the embodiment of the present display device
exemplified in FIG. 1 and discussed above, the display module 1 is
shown with an exemplary layout of the various user controls and
external signal input connectors. In additional alternate
embodiments of the display device the specific locations and layout
of each of these controls and connectors can be modified depending
on the needs of a specific type of market or application the
display device is targeted towards. By way of example but not
limitation, the sensitivity control dial 6 and or brightness
control dial 17 can be moved to a corner on the display module 1.
Furthermore, the specific types of controls and connectors used on
the display module 1 can also be modified to suit the specific
needs of the market or application the display device is targeted
towards. By way of example but not limitation, a rocker-type switch
can be used in place of a slider-type switch for the display mode
switch 5. By way of further example but not limitation, a
slider-type control can be used in place of a dial-type control for
the sensitivity control 6 and brightness control 17.
[0052] Referring again to the embodiment of the present display
device exemplified in FIG. 1, a variety of exemplary display modes
were discussed above. It should be noted that the display module 1
can be implemented with any particular combination of the
aforementioned different display modes and related external signal
input connectors. Hence, a variety of alternate embodiments of the
display device are possible whereby the combination of different
display modes and signal input connectors is selected to suit the
specific needs of the market or application the display device is
targeted towards.
[0053] It should be noted that any or all of the aforementioned
alternate embodiments may be used in any combination desired to
form additional hybrid embodiments. In addition, although the
subject matter has been described in language specific to
structural features and/or methodological acts, it is to be
understood that the subject matter defined in the appended claims
is not necessarily limited to the specific features or acts
described above. Rather, the specific features and acts described
above are disclosed as example forms of implementing the
claims.
